Threshold performance of GPS receiver for Space Shuttle applications
Abstract
The threshold performance of a GPS receiver in the Space Shuttle operating environment is found. This includes the threshold performance of three major receiver functions as determined by available signal-to-noise density ratio and Shuttle dynamics. These receiver functions are the mean time to slip for both the PN code tracking loop and the carrier Costas loop, as well as the probability of navigation data message error. The slip times are based on solutions to the Fokker-Planck equations for the loop probability density functions.
